ITF found in locking acquisition, LOW_NOISE_3_SQZ reached at 21:15 UTC. From remote M. Mantovani enabled the BS AA at around 23:20 UTC, Science Mode started at 21:26 UTC.
From around 0:40 UTC to 3:20 UTC the IMC_ref camera showed a visible oscillation of the beam. Also the power related to the Input Mode Cleaner started to decrease, but the Horizon seemed to remain unaffected ( see attached plot #1 ). The oscillation disappeared after the unlock.
ITF unlocked at 3:20 UTC ( see attached plot #2 ), I was able to reach LOW_NOISE_3_SQZ at 4:13 UTC but unlocked a minute later.
Relocking in progress.
